    摘要: An object of the present invention is to provide a dicing blade which does not cause cracking and breaking even in a workpiece formed from a brittle material, and can stably perform cutting process in a ductile mode on the workpiece with high precision. A dicing blade 26 which performs the cutting process on the workpiece is integrally formed of a diamond sintered body 80 which is formed by sintering diamond abrasive grains 82 so as to have a discoid shape, and a content of the diamond abrasive grains 82 of the diamond sintered body 80 is 80 vol % or more. It is preferable that recessed parts which are formed on a surface of the diamond sintered body 80 are continuously provided in an outer circumferential part of the dicing blade 26 along a circumferential direction.

    摘要: The present invention is a fixed-abrasive-grain wire including a core wire and abrasive grains fixed on a surface of the core wire, wherein an abrasive grain density is 1200 grains/mm2 or more, where the abrasive grain density is the number of the abrasive grains per unit area on the surface of the core wire, and 2% or less of all distances between centroids of the abrasive grains are equal to or shorter than an average circle equivalent diameter of the whole abrasive grains. There can be provided a fixed-abrasive-grain wire, a wire saw, and a method for slicing a workpiece that can suppress meandering of the fixed-abrasive-grain wire during slicing a workpiece and improve TTV and warp of wafers sliced from the workpiece.

    摘要: A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to bring each hook digit of the second holder in pressure abutment with the magnet block at a higher level than each hook digit of the first holder for thereby holding the magnet block in place on the platform.

    摘要: A front end portion of a core drill is formed in an arc shape in which longitudinal cross-sectional portions have the same radius. A contact width of a cutting edge of the core drill which first comes in contact with a surface of the glass sheet is small for the surface of the glass sheet, and the contact width of the cutting edge which comes in contact with the surface of the glass sheet is gradually increased as the core drill is lowered. An annular cavity into which the front end portion of the core drill is inserted is formed on an upper surface of the stage on which the glass sheet is placed. The annular cavity is formed so that its cavity width in the radial direction is wider than a drill width of the core drill.

    摘要: A programmable dicing saw is operable with movement of its spindle and work surface for aligning a dicing blade juxtaposed between flanges on the spindle and dicing a substrate along a predetermined blade path. By locating the center of the substrate, an efficient movement of the blade relative to the substrate center rather than the work surface center saves time. Locating the center of the blade includes aligning opposing substrate edges and edge location data entry into a processor for calculation of the substrate center and control based on the substrate center. In addition, prior to cutting along the edges of the substrate, the dicing blade is first aligned for travel parallel to and proximate the edge of the substrate, and an alignment offset is provided to the programmable dicing saw for laterally moving the blade toward the center of the substrate prior to making a cut and avoiding damage to the blade and substrate that typically results when the blade slides along the substrate edge rather than cutting into the substrate. In addition, by knowing the substrate center location, an arcuate cut can be accurately made into the substrate by making multiple straight cuts with a rotation of the substrate about its center between each cut. A flange clearance is monitored by measuring the blade exposure after a preselected number of cuts during the substrate dicing, and a minimum flange clearance permitted before blade movement toward the substrate is automatically stopped.
